Since we're hard up against the 9.5beta1 deadline, I've made an executive decision to commit just the minimal change, which I view as being to constrain the array size to MaxAllocSize where it has been all along. I found a second rather serious bug in the new hash code while doing that --- it failed to ensure nbuckets was actually a power of 2 --- which did not improve my opinion of it one bit. It's clear from this discussion that there's room for further improvement in the hashtable sizing behavior, but I think that's 9.6 material at this point. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
